It is common to find depictions of behaviorist approaches to the mind as approaches according to which mental events are “dispositions for behavior.” Moreover, it is sometimes said that for these approaches the dispositions are for publicly observable behaviors, or even “purely physical movements,” thereby excluding from being constitutive of mental events any internal bodily happening, besides any movement not taken as “purely physical.” In this paper I aim to pinpoint problems in such widespread depictions of behaviorism about the mind, (...) by arguing that they turn out to be too restrictive or too broad, as the case may be. In addition, I put forward an alternative, more balanced characterization, which wards off such problems. Based upon this alternative characterization, I attempt to classify some of the embodied mind theories as behavioral, non-behavioral, or borderline cases between behavioral and non-behavioral perspectives.

Physical cognition involves a host of cognitive abilities that enable understanding and manipulation of the physical world. Corvids, the bird family that includes crows, ravens and jays, are renowned for their cognitive abilities, but still little is known about their folk physics. This thesis explores the origins of physical cognition in corvids by investigating its mechanisms, development,fitness value and phylogeny in a wide context that includes theoretical and empirical studies.String pulling is a valuable paradigm for addressing these questions. Many animals (...) can pull a string with food attached to its end, but uncovering the cognitive abilities involved in this behaviour requires further testing. Paper I reviews the string-pulling paradigm, which is one of the oldest tests of animal cognition.It is a highly suitable test for species comparisons, socio-ecological correlations, and phylogenetic questions. Paper II tests several corvids, apes and peafowl on a string-pulling task where the first pulls do not result in the food moving closer. Despite the absence of such visual feedback, most subjects pulled strings in completely, although corvids appeared to choose randomly.Tool use is the archetypical example of physical cognition. Many corvids are remarkably adept at using tools in experimental settings. Paper III reviews animal tool use in general. It is now clear that customary tool-using species do not necessarily outperform their non-tool-using relatives on tests of physical cognition. For corvids that frequently use tools in the wild, such as New Caledonian crows and‘Alalā, tool use appears to have a significant fitness value and may have resulted in morphological adaptations. Paper IV describes a novel tool-use mode in New Caledonian crows. They inserted sticks into objects and then moved away,thereby transporting both. One crow could not grasp the target object, which suggests that such insert-and-transport tool use facilitates control over unwieldy objects. Paper V briefly argues that some corvids have shown the ability to make novel causal interventions, although this question should be addressed in a clearer theoretical framework that makes testable predictions.Sensorimotor cognition is a set of fundamental cognitive abilities that enables the integration of sensory and motor information into practical behaviour. It underlies much of corvid physical cognition. Paper VI investigates the development of sensorimotor cognition in ravens. Their skills developed rapidly and exceeded those of some mammals. They reached the same final sensorimotor stage as great apes, albeit at a markedly accelerated rate. The propensity of corvids to cache objects was investigated in Paper VII. Ravens, which often cache food,frequently cached objects, but surprisingly at similar rates as non-food-caching jackdaws. New Caledonian crows mostly cached objects that resembled functional tools.Anthropomorphism is the attribution of human traits to animals. Fear of mistakenly anthropomorphising animals has resulted in biased principles and an uneven burden of proof, which may hinder scientific progress more than it is supposed to offer protection against making mistakes. Cognitive zoology should not be misguided by overcompensating for such potential pitfalls. (shrink)

Despite its diminished importance amongst philosophers, the deductive-nomological framework is still important to contemporary behavioral scientists. Behavioral theorists operating within this framework must be careful to distinguish between nesting and chaining. Explanations are chained when the explanandum sentence of one explanation is one of the antecedent conditions of another. They are nested when one of the antecedent conditions or the explanandum sentence of one explanation is one of the covering laws of another. Confusion between nesting and chaining leads to explanation (...) nests that cannot be nomologically entrenched. They cannot, even in principle, be logically connected to laws arising from other sciences. This hazard should be particularly important for evolutionary psychologists to avoid, since many evolutionary psychologists tend to see themselves as dedicated to both nomological entrenchment and cognitive functionalist models. The hazard can be avoided if the intentional constructs of the behavioral sciences are construed not as ineffable and inaccessible antecedent conditions, but as complex, law-like patterns in behavior.
